I am trying to connect to DB from a shell script, but I am getting below errors for this.
Database output: ERROR:
ORA-12154: TNS:could not resolve the connect identifier specified
SP2-0306: Invalid option.
Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER}]

spool off
exit;

echo $var > ${LogDirectory}/DB_output.txt
Could you please suggest me how I will get the sql output in "var" variable, please? Thanks a lot !

Answer 1

The output of your query is getting spooled at below path
{LogDirectory}/query.txt
var will only have a status of code 1 or 0 . If the statement is executed successfully then var status will be 0 else 1.

Answer 2

It's working fine here:
#!/bin/bash
LogDirectory='/home/oracle'
ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_HOME
DBUSER='scott'
DBUSERPASSWORD='scott'
DB='db11g'
var=`$ORACLE_HOME/bin/sqlplus -S ${DBUSER}/${DBUSERPASSWORD}#${DB} << EOD
spool ${LogDirectory}/query.txt
set linesize 32767
set feedback off
set heading off
select 5 from dual;
exit;
EOD`
echo "Database output: ${var}"
$ ./stack.sh
Database output:
5
Is your database up and running? check:
ps -ef | grep pmon
This will show a process if it's running. When it's not you get the error you're getting:

Database closed.
Database dismounted.
ORACLE instance shut down.

edit for XING:
I changed the code to:
select * from t1;
$ ./stack.sh
Database output:
A
B
and select * from user_tables
$ ./stack.sh
Database output:
